Practice of sound Installing and placing tips
This chapter c ntains c mm n inf rmati n n
l udspeaker placement and installati n.
In which room do
you achieve the best
sound?
N matter h w g d the equipment is, in the wr ng
listening envir nment it will inevitably s und bad.
There are s me basic rules c ncerning a pr per
l udspeaker installati n:
Reflexions Carpets, curtains and s ft furniture abs rbs mid
range and high frequency s und, and this is
preferable. Big empty area, n the c ntrary, reflects
it and pr duces a hard s und that may lead t a
blurry dial gue. Apart fr m c l uring the s und,
als the perspective f the s und will deteri rate.
Reflecti ns in the r m can r ughly be c mpared t
the reflecti ns that yield gh st pictures n a TV
screen.
Amplification of bass
frequencies
A l udspeaker that is placed near a wall, ceiling r
fl r will be amplified in the l wer frequencies in a
s metimes n t desirable way (since it may lead t
an indistinct s und recreati n). This amplificati n
bec mes even m re bvi us if the l udspeaker is
placed near a c rner. Thus, f r a s und as clear as
p ssible, the l udspeaker sh uld be placed ab ut
30 cm (ab ut 12 inches) away fr m the wall.
H wever, there are excepti ns fr m this rule. F r
s me type f walls / r ms it may be advantage us
t place the l udspeaker cl ser t the wall.
Furniture Be aware that furniture may vibrate and thus create
bad s und at l ud bass.
Room dimensions Quadratic r ms r r ms where the length is
exactly twice as l ng as the width sh uld be
av ided, since they may create unwanted
res nance.
Placing the
loudspeakers
H w the l udspeakers are placed t wards the
listener is f great imp rtance.
The front speakers F r stere listening the l udspeakers sh uld be
placed symmetrically in fr nt f the listener. The
distance between the l udspeakers sh uld be ab ut
80% f the distance between the listener and ne
l udspeaker, r put in an ther way: the angle
between the l udspeakers, as seen fr m the
listener, sh uld be ab ut 45 degrees. This means
f r example that if the distance between the
l udspeakers is 2 meters, the listener sh uld be
placed 2,5 meters fr m the l udspeakers.
Angling? Either y u can have the l udspeakers angled in
t wards the listener r y u can have them directed
straight ahead. S me l udspeakers s unds better
when angled, but this may als depend n
